This is a 12-volt dual trumpet air horn from Marinco with a white epoxy coating. It is one of the maker's compressor driven air horns. It is rated at 121 dB(A) at one meter, and the two trumpets sound at fundamental frequencies of 375 Hz and 315 Hz, each plus or minus 15 Hz. The maker says its air horns meet ABYC and NMMA requirements for boats up to 20 meters (66 feet).
Our take
Two trumpets at 375 and 315 Hz, each plus or minus 15, make this a two-note horn rated 121 dB(A) at one meter. The maker ties its air horns to ABYC and NMMA rules for boats up to 20 meters (66 feet), so check your hull length against that claim.
From our buying guide
A boat of 12 m or more must have a whistle, and one of 20 m or more a bell as well. Under 12 m it need not carry them, but must have some other means of making an efficient sound signal.
Check before you buy:
- You aren't comparing loudness across makers, since they measure it at different distances, or give no distance at all.
- You can mount a fixed horn facing forward and as high as possible, as Kahlenberg says to.
- You have any parts the maker leaves to you, such as a horn button and fuse.
